lyap(A, C)

Computes the solution X to the continuous Lyapunov equation AX + XA' + C = 0, where no eigenvalue of A has a zero real part and no two eigenvalues are negative complex conjugates of each other.

In this example, the lyap function computes the solution X to the continuous Lyapunov equation AX + XA' + C = 0, where A is a 2x2 matrix and C is another 2x2 matrix.

The function returns the resulting matrix X, which satisfies the Lyapunov equation.

Note: The specific values in the example are arbitrary and provided for demonstration purposes. The actual values will depend on the input matrices A and C.
